Tamara BNPL for Business Central is a build-to-order AL extension that connects Microsoft Dynamics 365 Business Central directly to the Tamara split-payment gateway, so Saudi and GCC merchants can offer pay-in-3 and pay-later without leaving their ERP.

This is not an instant AppSource download. ECOSIRE builds the extension against your exact order-to-cash configuration, installs it as a per-tenant extension on your Business Central environment (cloud SaaS or on-prem), and supports it after go-live.

Under the hood, the extension adds a Tamara Setup page (API keys, merchant/store id, environment, fee G/L accounts, currency map) plus table and page extensions on Sales Order, Sales Invoice and the Customer card. AL event subscribers hook the document lifecycle: an OnAfterReleaseSalesDoc subscriber authorises the order against the Tamara API; posting captures it; a credit memo or cancel triggers a refund/void call. All gateway traffic runs through a typed AL HttpClient codeunit with retry, signature verification and a full request/response log table for audit.

Money lands correctly. A settlement reconciliation routine ingests Tamara payout reports, matches them to posted invoices, and posts Tamara's commission as a fee expense to the G/L account you nominate — so finance reconciles BNPL payouts like any other payment provider. Multi-currency is handled across GCC (SAR, AED, KWD, BHD, QAR) using BC currency codes and exchange rates.

Eligibility checks call Tamara at the cart/quote stage and surface approved limit and instalment plan on the document. A dedicated permission set, optional job queue entry for settlement polling, and Power Platform / Dataverse-friendly API pages round out the build. You own the source. ECOSIRE delivers, deploys and maintains it.
